Why Do Black Holes Actually ‘Suck’ Things In?

Imagine spacetime like a trampoline. When you drop a heavy ball on it, the surface bends around the ball. If something rolls close to the ball, it gets pulled toward it, just like how black holes ‘suck’ things in. The heavier the ball (or the black hole), the more it curves the trampoline (or spacetime). Things that get too close can't escape and fall into the center, where everything gets squished really tight.

Examples

  1. A black hole is like a heavy ball on a trampoline, anything near it gets pulled in.
  2. If you drop a marble into a deep well, it will fall all the way to the bottom and can’t come back out.
  3. Imagine being on a roller coaster that goes straight down into a pit with no way up.
